7 Be it known that I, Tnsnonus F. BA Li, a citizen of the United States, residing at Alliance,

of Shim have invented a Ainieeling-Furuaee, of is a specification.

This invention relates to annealing furneces and has more especial reference continuhus furnaces for annealing treating and the like.

T he object of this invention is to transfer heat from the out-going finished product to l -v.. material.

Another object isthe provision of an annealing furnace comprising a heating chamher and elongated regenerative hood and two trains of mateial moving in opposite new and useful which the follow ng directions through the hood and heating chamber.

tr'ith these objects in view the invention consists in the novel construction and arogenicnt of parts, hereinafter described, illustrated in the accompanying drawings and particularly pointed out in the. appended claims, it being understood that various changes in the form, proportions, size and minor details construction may he made Within the scope of the appended claims from the spirit or sacriaclvuntages of the invenficingi of the tion.

In the drawings: i is a plan View of the furnace.

erring" more especially to construe lustrate in the accompanying drevrings, she numeral 1 indicates the furnace which may be heated by any suitehie means although in the drawings eleetr'ic heating devices are shown. Resistance troughs 2 are provided in the heating chamsaid resistance troughs being composed a refractory material such as li re and contains a granular 1* indicated by the nuns; ctrocles 4 of the usual i Within the granular Specification of "Letters Patent.

material in the usual manner for thepun pose of comple 1g an electric circuit through the resistance niaterir.

A hood 5 of any desired 1. h communieates with said heatin urn-ace, su being open at its other entremi't to the outer air. A hood 6, Q "er to l is provided at the other e d of? t said hood open at its on end. i furnace is thus loo at suhssan center of the device.

It Will thus be seen the hoods and 6 produce a regenerative operation, the heat given off by the out-going mat rial instead or" being Wasted in'the outer air absorbed by the iii-going material while passin through the said hoods. e hoods may theigefore he specifically calied regenerative 1100 s. i v

For the salre o'" illustration the trains are shown in the drawings as made cars traveling upon the airs 8 i respectively the direction 0 rons shown thereon. Each oar 10 is i flat car provided with spaced transversely dis passages 11 to allow a circulation thhrethroug'h and packs 12 of me are carried upon said car"- as shownsuitable device he grovidecl t ing the trains of material through fun nace such for instance as the s which are operated through e by means of a motor 15. it W' l, 0 nor be understood that this speeliie pusher device has. no connection wit vention other than that some in ing the trains of material naoe B6QSSEY ';7. The cars material are moved from the 'es of 17, which trucks are designed to be moved laterally upon the tracks 18 until the cars are brought into alinement with the iii-going tracks, as shown in Fig. 1, after which theadjacent pusher is operated suficiently to move said car inside of the regenerative hood where it absorbs some of the heat from the adjacent out-going car from the other track. AS, this operation is repeated each particular car is successively moved stepby step through'the first regenerative'hood While the other train is being moved in the opposite direction, thus taking soment the heat from each car or unit of-mata'rial in passingthe same after whicheach car passes through the heating furnace and then in the same manner s passed step by step through the other regenerative hood giving up some of its heat to each adjacent iii-coming car or unit or material in the opposite ,train. By this process the in-going raw material conserves the heat from the out-going finished material, thatwould otherwise be lost were the train mi" finished 'niaterial run directly into the outside atmosphere and no regenerative hood used, thus the amount of heat necessary fOrthe'resisters within the heating furnace to supply, is greatly reduced, a large percentage of the heat carried out of the heating chamber by the finished -ing constructed of refractory and heat insulating material.

An annealing furnace consisting of a heating furnace and a regenerative hood and two trains of cars moving in opposite parallel directions through said annealing furnace and means for preventing loss of heat between the floors or" said cars and the trails of said furnace and hood.

6. A furnace of the character described comprising an enlarged heating chamber, an elongated regenerative hood communicating with each end of said heating chamber and two trains of material moving in opposite parallel directions through said regenerative hoods and heating chamber.
